There is thus all the more reason to exercise extreme vigilance ... against anything that may lead the being to become "fused," or preferably and more accurately "confused" or even "dissolved," in a sort of "cosmic consciousness" that shuts out all "transcendence" and so also shuts out all effective spirituality. This is the ultimate consequence of all the anti-metaphysical errors known more especially in their philosophical aspect by such names as "pantheism," "immanentism," and "naturalism."

Patiens quia æterna [patient because eternal] is sometimes said of spiritual authority, and rightly so; not of course that any of the external forms it may assume will be eternal, for every form is only contingent and transitory, but because in itself, in its true essence, it partakes of the eternity and the immutability of the principles; and this is why, in all conflicts that pit temporal power against spiritual authority, one can rest assured that, whatever the appearances may be, it is always the latter that will have the last word.

The relationship between these two powers may be expressed by saying that the pope must keep for himself the golden key to the 'Celestial Paradise' and entrust to the emperor the silver key to the 'Terrestrial Paradise'.
